Jerry Reinsdorf

Jerry Reinsdorf is an American businessman and one of the most influential sports team owners in the United States, controlling both the Chicago Bulls of the National Basketball Association and the Chicago White Sox of Major League Baseball. Born on February 25, 1936, Reinsdorf rose from a working class childhood in Brooklyn to become a tax attorney and real estate investor, and he used that fortune to buy the White Sox in 1981 and the Bulls in 1985. Across four decades he has presided over one of the greatest dynasties in basketball history and a long awaited baseball championship, making him a central and often debated figure in Chicago sports.

This profile covers who Jerry Reinsdorf is, his early life and education, his business career, his ownership of the Bulls and White Sox, his net worth and his current standing.

Early Life and Education

Jerry Michael Reinsdorf was born on February 25, 1936, in Brooklyn, New York, into a Jewish family of modest means. His father was a sewing machine salesman, and Reinsdorf has often spoken about his childhood as a passionate fan of the Brooklyn Dodgers, an early love of baseball that foreshadowed his later life as a team owner.

He left New York for his education, earning an undergraduate degree from George Washington University in 1957 and then a law degree from Northwestern University School of Law in Chicago in 1960. Northwestern brought him to the city that would become the center of his life and career, and after graduating he chose to stay in Chicago rather than return east.

Early Career as a Tax Lawyer

Reinsdorf began his professional life in tax law, working for the Internal Revenue Service early on and then in private practice. His expertise in tax and real estate proved highly valuable. He recognized opportunities in real estate investment partnerships, structures that offered tax advantages to investors, and he built a business around organizing and managing them.

In the 1970s he founded and grew a real estate firm, Balcor, which became a major sponsor of real estate investment partnerships. He sold Balcor to the financial services giant American Express around the early 1980s in a deal that made him wealthy and gave him the capital to pursue his real ambition, owning sports teams. His legal and financial sophistication would remain a hallmark of how he ran his franchises.

Buying the Chicago White Sox

In 1981, Jerry Reinsdorf led a group that purchased the Chicago White Sox, fulfilling a lifelong dream rooted in his boyhood love of baseball. As chairman, he became one of the most powerful owners in Major League Baseball, eventually playing an influential role in the sport's labor relations and ownership councils.

His tenure with the White Sox has been long and eventful. The franchise's defining moment came in 2005, when the White Sox won the World Series, their first championship since 1917, ending one of the longest title droughts in American sports. Reinsdorf has also drawn criticism at times for the team's spending and competitiveness, and his stewardship has been a frequent subject of debate among the team's fans. He has been a major force in baseball's business affairs, including its labor negotiations, for decades.

Buying the Chicago Bulls and the Dynasty

In 1985, Reinsdorf led a group that bought a controlling interest in the Chicago Bulls, a move that would tie his name to one of the most celebrated teams in sports history. The timing was extraordinary. The Bulls had just drafted Michael Jordan in 1984, and under Reinsdorf's ownership the franchise grew into a global phenomenon.

During the 1990s, with Jordan, Scottie Pippen and coach Phil Jackson, the Bulls won six NBA championships in eight years, becoming one of the most dominant dynasties in the history of professional sports and a worldwide brand. Reinsdorf, as owner, presided over this golden era, though his relationships with key figures, including the decision to break up the team after the 1998 title and contract disputes with stars and coaches, have been intensely scrutinized and dramatized, notably in popular documentary retellings of the era.

Jerry Reinsdorf Net Worth

Jerry Reinsdorf net worth was estimated at about $2.2 billion in 2025. The foundation was his early success in tax law and real estate, especially the sale of his real estate partnership business, but the largest driver of his modern wealth has been the soaring value of his two sports franchises. The Bulls and White Sox have each grown enormously in value during his ownership, in line with the broader explosion in the worth of major league sports teams.

Because so much of his wealth is tied up in the franchises and related real estate and media interests, the figure is an estimate that moves with team valuations. What is clear is that his decision to buy two Chicago teams in the early 1980s proved to be one of the most lucrative sports investments of his generation.

Personal Life

Jerry Reinsdorf has spent essentially his entire adult life in Chicago, where he is one of the most recognizable figures in the city's civic and sporting life. He was married to his wife Martyl for many decades until her passing, and he has children and a large extended family, with some family members involved in the management of his sports businesses. Despite his wealth and prominence, he has often been described as preferring a relatively low key personal style, with his public identity defined almost entirely by his two teams.

Achievements and Influence

Jerry Reinsdorf's achievements include presiding over six NBA championships with the Bulls and a World Series title with the White Sox, a remarkable haul for a single owner across two sports. Beyond trophies, he has been one of the most powerful voices in the business of American sports, influential in baseball's labor and ownership matters and in the construction of stadiums and arenas in Chicago, including the building of what is now the United Center and the White Sox ballpark. He has been recognized with induction into the Basketball Hall of Fame for his contributions to the game.

Jerry Reinsdorf in 2026

As of 2026, at age 90, Jerry Reinsdorf remains the controlling figure behind the Chicago Bulls and Chicago White Sox, though questions about succession and the long term future of his ownership are a constant topic in Chicago. The themes around him include the competitiveness of both franchises, the future of their stadiums and the eventual transition of control of two of the most storied teams in American sports.
